Which type of power refers to energy that passes through reactive components without consuming energy?

The type of power that refers to energy passing through reactive components without consuming energy is reactive power. Reactive power is associated with the energy that alternates between the source and the reactive components of an electrical system, such as inductors and capacitors, rather than being consumed or converted into useful work.

In alternating current (AC) circuits, reactive power is crucial because it helps maintain the voltage levels necessary for active power to do useful work. This reactive power can lead to energy storage in magnetic or electric fields but does not result in energy being consumed. It is measured in volt-amperes reactive (VAR). This makes reactive power distinct from forms of power that do contribute to actual energy consumption and performance in a circuit.
